Made this update for personal use, so there might be little tweaks here and there. Ages and so on unchanged since I was always going to simulate closer to present day before playing. I treated every loan transfer (where applicable) as a permanent one to make the editing faster/simpler. For the same reason youth players only appear when they were already in the db I used as a starting point. (Created Donnarumma, Ousmane Dembele and Leroy Sane)
